Jeremy agreed to sell 10,000 widgets to Nancy at $100 per widget. Before Jeremy was about to tender the widgets, Nancy told Jeremy that she would not take the widgets. Jeremy then sold the widgets for $75 per widget on the open market. Jeremy sued Nancy for the difference (i.e., $25 per widget). Nancy counters that she was not notified of the resale on the open market and is therefore not liable. Who is correct? Why?
